2006 Lincoln Navigator air suspension

ok this is my situation. My car was down in the front right side. I went to the shop and they said both air bags suspension were defective and they suggested to replace the suspension by springs kit. after the work done I had two problems in cluster, "check suspension" and "check Advtrack" messages always alternating, also the light for Advtrack system flashing for a while until stays on. I looked for information in internet and found the solenoids should be left installed. I went back and the solenoids were left in place, the "check suspension" message appears to be missing, but the Advtrack message and light continue the same. what can I do? thanks
